安装环境是 Win10下 的 VMware16.2
本次安装用的是从
http://cdimage.debian.org/cdimage/archive/10.12.0-live/amd64/iso-hybrid/
页面下载的
debian-live-10.12.0-amd64-standard.iso
开启网卡时,安装会比较慢, 所以禁用了网卡
或者点右下角网络图标,断开连接
选择语言, 中文在本地控制台无法显示, 选其它语言又不好选时区, 所以可以选择第一个, no localization 无定位
让后选 Asia 亚洲
Debian10Standard的iso镜像没有apt仓库功能, 无网安装后, 没法使用 apt update
sudo vi /etc/apt/sources.listsudo nano /etc/apt/sources.list查看此时的apt镜像配置文件

Debian10.12Standard自带两种网络服务 networking 和 systemd-networkd , 没带 NetworkManager
默认启用了networking 没有启用 systemd-networkd
分别查看状态
查看 systemd-networkd.service
sudo systemctl status systemd-networkd
说明有systemd-networkd.service这项服务,但没有启用, 所以没有启动
查看 networking.service
sudo systemctl status networking
networking启用了,但没启动成功
没有启动成功的原因是 /etc/network/interfaces.d/setup 这个文件的设置.
将两个eth0改为 ens33 (刚开始时,vim不好用, 可以用nano编辑文档)
sudo nano /etc/network/interfaces.d/setup
也可以用 sed 命令修改
sudo sed -ie 's/eth0/ens33/g' /etc/network/interfaces.d/setup/etc/network/interfaces.d/setup 是由 /etc/network/interfaces 调用的, 并不是每个版本都有这个文件
也可以删掉/etc/network/interfaces.d/setup , 直接修改 /etc/network/interfaces
修改后 systemctl restart networking , networking可以启动了
可以自动获取ip了
为方便复制粘贴, 须开启ssh远程控制台, 须安装openssh-server , 但这张光盘iso却没有自带, 有些麻烦
一种方法是加载有openssh-server的光盘iso, 比如http://cdimage.debian.org/cdimage/archive/10.12.0/amd64/iso-cd/debian-10.12.0-amd64-xfce-CD-1.iso , 然后执行 apt-cdrom add命令, 然后执行 apt install openssh-server命令
另一种方法是编辑/etc/apt/sources.list, 添加好用的源, 然后执行 apt install openssh-server命令
默认的vim有问题, 编辑模式下,上下左右和退格键都不好用
用 nano 打开 /etc/vim/vimrc.tiny
sudo nano /etc/vim/vimrc.tiny将 set compatible 改为 set nocompatible 再加一行 set backspace=2 ctrl+o回车保存, ctrl+x退出
原先的 /etc/vim/vimrc.tiny
" Vim configuration file, in effect when invoked as "vi". The aim of this
" configuration file is to provide a Vim environment as compatible with the
" original vi as possible. Note that ~/.vimrc configuration files as other

set nocompatible
set backspace=2
" vim: set ft=vim:这下上下左右退格就正常了 ,
但远程连接时发现,这个版本的vim会捕获鼠标, 导致没办法复制粘贴 !!!
- 解决方法1 :
sudo vi /usr/share/vim/vim81/defaults.vim找到 /usr/share/vim/vim81/defaults.vim 的
if has('mouse')
set mouse=a
endif修改为 mouse-=a 或 mouse=r 或者干脆去掉这句
用脚本修改
sudo sed -ie 's/set mouse=a/set mouse-=a/g' /usr/share/vim/vim81/defaults.vim- 解决方法2:
sudo /etc/vim/vimrc在末尾加上
let skip_defaults_vim = 1 " 跳过default.vim
if has('mouse')
set mouse=r
endif或只加上第一句
let skip_defaults_vim = 1跳过那个默认配置文件的设置
Debian10Standard 自带 networking和systemd-networkd两种服务可配置网络
-
networking的配置文件是/etc/network/interfacesnetworking可搭配resolvconf配置DNS
或者用/etc/network/interfaces和/etc/resolv.conf实体文件 分别配置 IP 和 DNS -
systemd-networkd的配置文件是/etc/systemd/network/*.networksystemd-networkd可搭配systemd-resolved配置DNS
也可搭配/etc/resolv.conf实体文件 分别配置 IP 和 DNS
用 /etc/network/interfaces 设置静态Ip
sudo vi /etc/network/interfaces无网络安装的初始的 /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback有网络安装的初始的 /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo

# The primary network interface
allow-hotplug ens33
iface ens33 inet dhcp可以看到 source /etc/network/interfaces.d/* 这句会执行 /etc/network/interfaces.d/ 下的所有脚本/etc/network/interfaces.d/ 里一开始有个 setup 文件
sudo vi /etc/network/interfaces.d/setup无网络安装的初始 /etc/network/interfaces.d/setup
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp有网络安装的初始 /etc/network/interfaces.d/setup
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp可看出 /etc/network/interfaces.d/setup 有网无网安装都没区别.
而且其中eth0并不存在, 会使networking 报错 , 还有与/etc/network/interfaces重复的部分
可以删除这个setup文件, 直接在上级目录的 interfaces 文件中配置
也可以把 setup 改成
auto ens33
iface ens33 inet static
address 192.168.168.10/24
gateway 192.168.168.2或
auto ens33
iface ens33 inet static
address 192.168.168.10
netmark 255.255.255.0
gateway 192.168.168.2最好是删除setup,避免和interfaces内容冲突
也可参考官方版本 https://wiki.debian.org/NetworkConfiguration 的
/etc/network/interfaces

vlan-raw-device bond0经测试, 默认情况下, 通过设置 dns-nameservers 来设置DNS没用,
默认也没有安装resolvconf这个程序
官方文档说,如果安装了resolvconf这个程序, 就不要修改 /etc/resolv.conf ,
sudo apt install resolvconf而用dns-nameservers 来设置DNS
安装了 resolvconf 后, 就会有 resolvconf.service 服务, 默认没有启动
sudo systemctl enable resolvconf
sudo systemctl start resolvconf安装了 resolvconf 后, /etc/resolv.conf 变成一个符号链接(软链接) ,不要直接修改它
sudo vi /etc/resolv.conf无网络安装时, 没有 /etc/resolv.conf
有网络安装的初始 /etc/resolv.conf
domain localdomain
search localdomain
nameserver 192.168.168.2如果没有安装resolvconf这个程序 , 可以自己创建一个 /etc/resolv.conf
nameserver 192.168.168.2
search baidu.com或
nameserver 192.168.168.2
domain baidu.comsearch是搜索域, 作用如:设置baidu.com后, ping www 就能达到 ping www.baidu.com的效果
它在域名没解析到时起作用, 追加设置的后缀再请求DNS解析一遍search是domain的替代,效果一样,
-
search可以设置多个值,用空格分隔 , -
domain只能设置一个值
如果安装了resolvconf这个程序, /etc/resolv.conf 变成一个符号链接(软链接) ,不要直接修改它

没那么多精力研究清楚
已知的设置ip工具有: network , networking , NetworkManager , systemd-networkd , netplan
用 network-manager(NetworkManager) 配置静态Ip
一般图形界面的Linux本身就带NetworkManager, 命令行界面的可能不带
debian10Standard用apt安装NetworkManager要用network-manager
sudo apt install network-managersudo systemctl enable NetworkManager
sudo systemctl start NetworkManager安装好后, systemctl status NetworkManager和systemctl status network-manager 效果是一样的
安装好NetworkManager后就能使用nmtui和nmcli命令配置网络
nmtui可以使用命令行的图形界面来配置网络
用 NetworkManager 的 nmtui 配置网络
也可以用 nmcli 命令行语句配置网络
用 NetworkManager 的 nmcli 配置网络
-
nmcli connection add可以创建一个新连接配置 -
nmcli connection modify可以修改现有连接
nmcli connection 的 add和modify 的 ipv4 选项
-
ipv4.可以接 [method, dns, dns-search, dns-options, dns-priority, addresses, gateway, routes, route-metric, route-table, routing-rules, ignore-auto-routes, ignore-auto-dns, dhcp-client-id, dhcp-iaid, dhcp-timeout, dhcp-send-hostname, dhcp-hostname, dhcp-fqdn, dhcp-hostname-flags, never-default, may-fail, required-timeout, dad-timeout, dhcp-vendor-class-identifier, dhcp-reject-servers] 。
-
ipv4.method的可选]值有 [auto, link-local, manual, shared, disabled] ,ipv4.method最简可写成ipv.me -
ipv4.addresses设置IP地址, 最简可写成ipv4.a, 可设置多个地址,以逗号分隔, 也可多次用+ipv4.aipv4.a(ipv4.addresses)可以设置多个(,逗号分隔,可以有空格),但只能出现一次,+ipv4.a(+ipv4.addresses)可以设置多个(,逗号分隔)可以出现多次 - 网关
ipv4.g(ipv4.gateway)只能有一个, (在图形界面也只能设置一个), 如果没设置网关就不能上网,但只要有ip地址,就能让网段内其它主机访问,比如ssh连接,没有网关就是能进不能出 -
ipv4.dns不能简写,可一次设置多个,+ipv4.dns可多次设置多个 -
ipv4.dns-search可简写为ipv4.dns-s, 搜索域 -
ipv4.ignore-auto-dns取值true|fasle是否跳过自动域名 , 最简只能写成ipv4.ignore-auto-d
nmcli connection add 可以创建一个新连接配置
nmcli connection add 可以简写为 nmcli c a
sudo nmcli c a con-name 'Test001' ifname 'ens33' type ethernet ipv4.method 'manual' ipv4.addresses "192.168.168.8/24 , 192.168.168.225/24,192.168.168.226/24" +ipv4.address '192.168.168.227/24' +ipv4.a '192.168.168.228/24' +ipv4.addre '192.168.168.229/24 , 192.168.168.230/24 , 192.168.168.231/24' +ipv4.addr "192.168.168.232/24" +ipv4.ad '192.168.168.233/24' +ipv4.a 192.168.168.234/24,192.168.168.235/24 ipv4.gate 192.168.168.2 ipv4.dns 192.168.168.2,119.29.29.29,180.76.76.76,223.6.6.6,8.8.4.4,114.114.115.115 +ipv4.dns '223.5.5.5 , 8.8.8.8 , 1.1.1.1 , 114.114.114.114' +ipv4.dns 101.226.4.6,123.125.81.6 ipv4.ignore-auto-dns true ipv4.dns-search baidu.com,aliyun.com,taobao.com,qq.com,google.cn上面的命令会生成 /etc/NetworkManager/system-connections/Test001.nmconnection

nameserver 192.168.168.2
nameserver 119.29.29.29
nameserver 180.76.76.76
# NOTE: the libc resolver may not support more than 3 nameservers.
# The nameservers listed below may not be recognized.
nameserver 223.6.6.6
nameserver 8.8.4.4
nameserver 114.114.115.115
nameserver 223.5.5.5
nameserver 8.8.8.8
nameserver 1.1.1.1
nameserver 114.114.114.114
nameserver 101.226.4.6
nameserver 123.125.81.6可能只有前3个DNS会生效
如果使配置生效过程中出现 device is strictly unmanaged 而没法生效
可查看/etc/NetworkManager/NetworkManager.conf
sudo cat /etc/NetworkManager/NetworkManager.conf[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false将 managed=false 改为 managed=true
sudo vi /etc/NetworkManager/NetworkManager.conf[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
managed=true👆可以直接将 managed=true 加在 managed=false 下面
重启 NetworkManager
sudo systemctl restart NetworkManager

sudo nmcli connection reload使配置生效
sudo nmcli connection up Test001安装openssh-server , 更换apt源
一种方法是加载有openssh-server的光盘iso, 比如http://cdimage.debian.org/cdimage/archive/10.12.0/amd64/iso-cd/debian-10.12.0-amd64-xfce-CD-1.iso , 然后执行 apt-cdrom add命令, 然后执行 apt install openssh-server命令
另一种方法是编辑/etc/apt/sources.list, 添加好用的源, 然后执行 apt install openssh-server命令
